Abstract
An integral electronic meter system diagnostics package including a microprocessor, storage memory, pre-select series of system diagnostic tests, and recording any results which exceed predefined programmable thresholds, and display means for displaying error and/or diagnostic messages identifying selected diagnostic data and/or errors discovered in the meter tests during a predefined period. The system automatically senses the type of electrical service in which the meter is installed.
Claims12
An electronic meter checking an electrical system diagnostics package including:
- a microprocessor;
- storage memory suitably connected to the microprocessor;
- logic for automatically periodically performing a preselected test of meter checks and recording any errors detected therefrom;
- logic for automatically periodically performing a preselected series of system diagnostics tests and recording any results which exceed predefined thresholds;
- display means for displaying error messages identifying one or more errors discovered as a result of the meter checks performed during a predefined period;
- and
- display means for displaying diagnostic messages identifying any errors discovered as a result of the system diagnostics tests performed during a predefined period.
An electronic meter system checking and troubleshooting package for ascertaining voltage information from a polyphase electrical system metered thereby, including:
- (a) a microprocessor;
- (b) storage memory suitably connected to said microprocessor and
- (c) logic for automatically determining the type of polyphase electrical system in which a meter including the system checking and troubleshooting package is installed.
